Is it worth visiting the Sistine Chapel or going to the Louvre or the Hermitage? Who knows!

But it is completely different from seeing pictures of them.

What books are worth it? Hmmm. Depends. But some are very much so.

Is The Art of Computer Programming worth it? Is little Rudin worth it? Is the “Feynman lectures on Physics” worth it? Is “The Ides of March” worth it?

Depends.
